It’s also because the approval isn’t about the grade it’s about the minimum HT/HS. Grade is irrelevant in this instance. Go with the approval and forget about the grade.Thanks for the reply. My current fill is PP LX 0W-30 and it's closing in on 5,000 miles. I'm going to drain it and send it in and fill it with either
Mobil 1 ESP 0W-40 or something similar. I can't seem to find any 40W oils that are VW 504 approved, any idea why that is?
